y UNITED STATES PATENT (NEIGE.

VILLIAM A.' LIGIAI'IHALL, `OF NEW' YORK, N. Y.

Y Specification forming part-of Letters Patent No. 35,319, dated May 20,1862.

To @ZZ whom it may concern:

Be it known that I, WILLIAM A. LIGHT- HALL, of the city, county, andState ot' New I York, have invented a certain new and usefulImprovementin Condensers for Making P0- table Water fronISalt or otherUnpotable Vater; and I do hereby declare that the follow- -in g is afull and exact description of the same,

reference being had to the accompanying drawings, wand to the letters ofreference marked thereon, in which* Figure 1 is a side elevation; Fig.`2, a central longitudinal vertical section; and Fig. 3,

a cross-section taken through the line ocx, Fig. 2. .n

My inventionv is a further improvement upon theones secured to me byLetters Patent of the United States bearing date of December 17, 1861,and April 22, 1862; and it consists in dispensing with .the drip-plateshown and described therein, (to which reference is hereby made) andsubstituting therefor a water-bed to serve the purpose thereof inchanging the direction of the current of steam received into thecondenser to pass between the'division-plates, and also to serve toreceive the water of condensation, as set forth in the Letters Patentabove named. The case of the condenser, its division-plates, and tubesand reservoir being constructed and arranged as set forth in the LettersPatent above named, the alterations (constituting, in

combination with the above, my improvement) are in dispensing with thedrip-plate therein shown andfin so arranging and constructing thedischarge-pipe A, for the discharge of the water of condensation., as toretain within the bottom Vpart of the condenser (forming the reservoirthereof) a sufficient quantity of the water of condensation to cover thelower ends of the division-plates B B', so that the steam entering intothe condenser through the nozzle C shall be passed yfrom section tosection the same as though the drip-plate aboveY named were used, thedischarge-pipe taking oft' the colder water that collects at the bottomof the reservoir at the same time that it V\VM.
